Mutations

Mr. Anderson discusses mutations, which are changes in DNA that can affect proteins and, ultimately, organisms. He uses a recipe analogy to explain point mutations and their effects. Mutations can be spontaneous or induced by environmental factors. Various types of mutations, such as substitution, deletion, and translocation, are explored, highlighting their potential impacts on chromosomes and genes.

How can environmental factors lead to mutations in DNA?

What is a substitution mutation and why can it be problematic?

What are some examples of larger mutations that can occur in chromosomes?
